Abstract :
Mobility between dissimilar networks is one of the future trends in network design towards fourth generation of telecommunication systems. A cellular network can be overlaid with a spottish high data-rate WLAN network in areas such as business centers, hotels and airports. To avoid unnecessary search of WLAN beacon the terminal must be aware of the whereabouts of the overlay system to be visited. We suggest the usage of geolocation information in mobility management via distributed location databases to enable a moving host to prepare for handoff. Three scenarios and the related problems are presented, and the requirements for the system architecture and terminal are outlined. Considerations on the algorithm are given and preliminary simulation results of a fuzzy logic handoff algorithm are presented
